Aircraft scheduling is an important factor affecting the operating costs of airlines. Dispatching aircraft reasonably can not only maximize the benefits of the aircraft utilization, but also reduce flight delays. In this paper, we first transfer the scheduling model to the postman problem with the network model. Then, a scheduling model that use minimal aircrafts under the giving flight plan is put...
Near space aircraft enters a glide phase after the boost phase. A low glide altitude can reduce the hostile warning time to enhance penetration possibility. Therefore a lower boost phase altitude is favorable. The trajectory optimization of the boost phase for a three-stage solid rocket is an optimal control problem subject to various constraints. This problem is reformulated as a nonlinear programming...
